Electronics For 38MM Coupling Tube?

Dec 12, 2003 9 Replies

Any suggestions for an altimeter to fit inside a 38mm coupling tube.

I flew my Perfect Flite minialt/wd in a 38mm bay made out of loc coupler and two bulk heads with a #6 threaded rod holding the bulk heads together. it flew dual deploy to 6742 on an Ellis Mountian I-134 long Burn motor. It's only $99 It logs the whole flight and you can download the data.

If you only want to log the flight, the alt15k from perfect flight is only $69 and fits a BT-20 tube !

I did a LOC Legacy that housed a Adept ALTS2. Very tight fit but definetly doable. Perfectflight has a dual deployment alt thats even smaller than the ALTS2 that should fit like a breeze.

How high do you plan on going? (Some good altimeters only go to 15K, or 25K).

How much verticle room do you have?

Do you want the altimeter to do anything else? (Like fire a chute, or dual-deployment)

How much money do you have? ;)

IMHO, get a flight computer.

Is your rocket a Hybrid? (R-DAS used to have problems with Hybrids)

25k on a 38mm with any reasonably expected AT or EX motors? Bah!

Ahhh... but it *could* be the third stage of a much bigger rocket, eh?

That would be sweet indeed.

The Missile Works RRC2 fits perfectly in a 38mm coupling tube. Their PDF instructions even give some guidelines about constructing such an electronics bay. Refer to:

Exactly why I choose the RRC2. This way I have a modular Bay that can simply slip into any rocket that I build.
